AIR WASHER.

,Specification of Letters Patent.

Patented Apr. 4, 1922.

Application filed March 3, 1919. Serial No. 280,327.

Washers, of which the following is a speciv fication.

My invention is an improvement inair washers, and has for lts ob ect to provide a device of the character specified adapted for use with internal combustion engines, wherein a container for water is provided, through which the air must pass, and wherein means is arranged in the container for constraining the air to pass through the water to thoroughly wash the same and remove impurities therefrom when the engine is working, and wherein the constraining means is arlanged to permit the air to pass directly into the container above the water to furnish dry atmospheric air to absorb the moisture in the container when the engine is not running.

It is also an object of the invention to provide an air washer for internal combustion engines for automobiles, tractors,

and thellike, which obviates the necessity of employing closed chambers or floats, which are very sensitive to the disturbance of the water level, as in travelling over uneven surfaces.

In the drawings:

Figure 1 is a vertical section through the purifier; I

Figure 2 is a side View showing the position of the parts in dotted lines when the engine is not running;

Figure 3 is a similar view when the engine is working;

Figure 4 is a top plan View.

In' the present embodiment of the invention, a container 1 is provided of suitable size and of cylindical form, consisting of upper and lower sections 1 and 2 which are detachably connected by bolts and nuts, as shown at 3, to -form a closed receptacle, and at the center of the bottom of the lower sec- ,tionthere is an upwardly extending nipple 4, through which the air is adapted to enter the casing.

At one side of the lower section there is an internally threaded drain port 5 which is normally closed by a plug 6 threaded into the port, and near the top of the lower section at the same side thereis a filling inlet 7 normally closed by a plug, \as shown. The upper sect on has at its top and atthe opposite side from the drainport an out- I let 8 with which may be connected a pipe for leading the washed air to the place of utilization, that is, to the carburetor.

A cap 9 is arranged over the nipple, 4, the said cap being of greater diameter than the n pple, and this cap is provided in its top with a port or opening. This cap is of suitable sheet metal, and its has a acketed petticoat intermediate its ends, the said petticoat consisting of outer and inner walls 10 and 11. The walls of the petticoat are spaced further apart at their connection with the cap wall, and the jacket formed between the walls communicates with the interior of the cap by an annular series of openings 12. It will be noticed that the inner wall 11 extends below the outer wall, at the bottoms of the said walls, and the said inner wall curves outwardly as shown to deflect the air in the same direction. The inner Wall has outwardly oflsetbeads 14 for spacing the two walls apart, and rivets 1 1 are provided in the cap at its lower end for preventing the lower edge of the cap from striking against the nipple 4. The valve 15, which is adapted to close the port 17 in the top of the cap,

is normally opened, being supported by a.

cage 16, and a sheet 18 of gauze is arranged over the opening at the upper end of the port, the valve closing against the lower end.

In operation, when the engine is not runarts occupy the dotted-line posi;

tween the cap and the wall of-the etticoat; into the water, passing again upwardly through the water to the outlet. Thus, the air is thoroughly washed and purified by the water. When the air passes downwardly between the cap and the petticoat, the water will have become displaced from such space by the raising of the cap due to the depression in the container or casing above the water by the suction of the engine. As soon as the proper engine speed is obtained, depression is created above the water level in the tank, the atmospheric pressure of the gravity to an open position and will remainin this position until the motor is started.

As soon as there is suction in the container,

, the valve closes and the air passes through the water.

No float is needed, since the suction always holds-the cap in the proper position, the air chamber between the cap 9 and the wall 11 serving to properlybuoy up the cap or washer, the size and weight of the parts being so proportioned as to give a proper balance to permit the rise and fall thereof when the engine or motor is running, and when stopped, the rise and fall of the cap compensating for the variation in the water level, as the water in the container or casing istaken up or consumed in use, it being understood that tho water level is normally adjacent to the filling plug 7 and lowers on continued use. The arrangement of the hollow petticoat forces the air to divide evenly. The space beneath the petticoat serves as a reserve for air, and helps the air washer to hold a permanent position when the engine is at work at the proper level and at the proper depth. The inner wall of the petticoat deflects the air outwardly through the Water. Rivets '14, it will be noticed, are passed through the cap at its bottom, for engaging the nipple to prevent wear on the cap. hen the engine 1s running the valve 15 serves as relief valve opening outwardly when there is undue back pressure in the tank, as, for instance, from pre-ignition.

I claim: p
